Sidereal Time is a convenient way for astronomers to keep time since it’s based on the daily and nightly motion of the stars across the sky, rather than the Sun. The time on your wristwatch or the clock is based on the Solar Day- Civil Time is one way to refer to this timekeeping method. Like the Solar Day, Sidereal Time is divided up into 24 hours, each with 60 minutes.

A sidereal day is slightly shorter than a mean day, lasting 23 hours, 56 minutes, and 4.1 seconds. A sidereal day is divided into 24 sidereal hours, which are each divided into 60 sidereal minutes, and so on. The reason that sidereal days are shorter is that while the Earth rotates on its axis, it is also moving around the Sun.

(0.683 sidereal days) x (23.9345 hr/sidereal day) = 16.347 hr = 16 hr 21 min. (i.e., a sidereal clock at noon solar time on November 29 reads 4 hr 21 min ahead of a solar clock).

Sidereal time is based on when the vernal equinox passes the upper meridian. This takes approximately 4 minutes less than a solar day. 1 sidereal day = 23 hours, 56 minutes, 4.1 seconds. Sidereal time is useful to astronomers because any object crosses the upper meridian when the local sidereal time is equal to the object's right ascension.
